The term protozoa is used for a diverse and very big group of organisms with more than 65,000 known species of single celled creatures that display unique features for movement, feeding and behaviour. Most protozoans are harmless and free-living, but a few species are parasitic and cause major health concerns in humans. Protozoa are divided into four groups, out of which the members of group Apicomplexa (Sporozoa) are known to form spore like cells (sporozoites).

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?

Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to. What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?

Does the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo? Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?
